efa-m - Unofficial interface to the efa.vrr.de departure and trip monitor

version 3.03
efa-m is an interface to EFA public transport services.
It can serve as a departure monitor, request details about a specific trip/journey, and look up public transport stops by name or geolocation. The operating mode depends on the contents of its mandatory argument.
Shows departures it name or city name. For each departure, efa-m shows
If city is specified, name refers to a location within city. Otherwise,
name must be self-contained. I.e., both efa Essen Hbf and
efa "Essen Hbf" are valid. Note, however, than efa E Hbf works,
but efa "E Hbf" does not.
By default, name refers to a stop, this can be changed by specifying type. Supported types are address and poi (point of interest).
List stops that match query or that are located in the vicinity of lat:lon geocoordinates.
List trip information as well as arrival and departure time, name, and platform of each stop on the trip's route.
Values in brackets indicate options that only apply to the corresponding operating mode(s).
Probe all known EFA entry points for the specified stop. Print the first result which was not an error.
Note that this may take a while and will not necessarily return the best result. Also, using thi option by default is not recommended, as it puts EFA services under considerable additional load.
Show departures for date instead of today. May also be specified as dd.mm.
Probe all known EFA entry points for the specified stop. Print the URLs and names of all entry points which did not return an error.
Show journey ID for each departure. The ID can be used to query details with a subsequent efa-m invocation (trip details mode).
Print result(s) as JSON and exit. This is a dump of internal data structures and not guaranteed to remain stable between minor versions. Please use the Travel::Status::DE::EFA(3pm) module if you need a proper API.
Do not show departures. Instead, list all lines serving the specified place. Note that this information may be incomplete -- only lines which are in service either at the time of the efa-m call or at the time specifed using --date and --time are guaranteed to be included.
Only show departures of lines (comma-separatad list, option may be repeated)
List supported EFA services with their URLs (see -u) and abbreviations (see -s).
Only show departures whose type appears in motlist (comma-separated list, this option may be repeated).
The following departure types ("modes of transport") are supported: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus, schnellbus, seilbahn, schiff, ast, sonstige
Ignore departures which are less than minutes from now.
For each result, show additional information as specified by outputtypes. outputtypes is a comma-separated list, the -O/--output option may also be repeated. Each output type has both a short and long form, for instance both "-Or" and "--output=route" are valid.
The following output types are supported:
Show each departure's full route (timestamps and stop names) after the requested station.
Show each departure's full route (timestamps and stop names) before the requested station.
Show each departure's full route (timestamps and stop names) before and after the requested station.
Show station-specific information messages. These typically relate to construction work, broken elevators or escalators, or special announcements for large-scale events.
Show up to three stops between the requested station and the departure's destination. efa-m tries to display the three most important stops, however these are heuristically determined and may not be optimal.
Show free-text messages associated with individual departures. These can include generic information such is bicycle transportation options or Wi-Fi availability, delay reasons, and more.
Only show departures at platforms (comma-separated list, option may be
repeated). Note that the Bstg. / Gleis prefix must be omitted.
Show relative departure times in minutes (i.e. the time difference between the departure and the time of the request). In this case, realtime data is already included.
Short name of the EFA entry point. See Travel::Status::DE::EFA(3pm) and the --list option for a list of services.
Show departures starting at time instead of now.
Set timeout for HTTP requests. Default: 10 seconds. Set to 0 or a negative value to disable it.
Only show trains serving station after the requseted stop, and show the arrival time at station after the departure time at the current stop. station is matched against the "city stop" fields in each line's route. Regular expressions are also supported.
Show version information.
Normally zero. 1 means efa-m was called with invalid options, 2 indicates a request error from Travel::Status::DE::EFA(3pm).
None.
efa-m uses the VRR EFA service by default, which seems to contain the greatest available set of information. However, some cities (e.g. Berlin or parts of Hamburg) are not supported there, and efa-m is not yet able to choose the appropriate EFA URL for these by itself. In these cases, you should find an appropriate EFA service using the -D/--discover option and then use -s service when making requests.
